Load distribution after synchronisation
The difference between the frequencies of the sources is low. The load distribution therefore does not change much when the
breaker closes.
5.4.3 Regulator synchronisation parameters
During synchronisation the controller regulates the governor to change the frequency and phase angle. These settings are only used
during synchronisation, and can be configured to optimise the synchronisation speed for the system.

0 s to 1 min 2.5 s
The PID control integral time.
To turn off the integral component, set Ti to 0. This might cause unexpected regulator
behaviour.
